Tom Kelly's Coward Punch Killer Charged Over Jail Fight

The NSW man behind bars for fatally punching Thomas Kelly in Kings Cross nearly five years ago has been charged following an alleged attack on an inmate in a western Sydney jail.

Kieran Loveridge, 24, allegedly approached a 34-year-old inmate at Silverwater jail on Monday and punched him in the face before they began wrestling.

The pair was separated by corrective service officers, with the older inmate treated for facial injuries, a NSW Police spokeswoman told AAP on Wednesday.

Police criminal group Strike Force Raptor investigated the attack and charged Loveridge with affray on Tuesday.
